Abstract
A stability control augmentation system and method for a flight control surface of an aircraft. The system includes s an actuator operable for actuating the flight control surface, and a control valve comprising a spool and an integrated augmentation mechanism. The spool and the actuation mechanism are both moveable to open and close a fluid flow path through the control valve to control the actuator.
Claims12
A stability control augmentation system for a flight control surface of an aircraft, comprising:
- an actuator operable for actuating the flight control surface;
- and
- a control valve comprising a spool and an integrated augmentation mechanism, wherein the spool is moveable to increase or decrease a cross-section of a fluid flow path through the control valve to thereby increase or decrease a flow of hydraulic fluid to the actuator during use, and wherein the integrated augmentation mechanism is operable to increase or decrease the cross-section of the fluid flow path to thereby adjust the flow of hydraulic fluid to the actuator;
- wherein the control valve comprises a rocking pin connecting the spool and the augmentation mechanism, wherein the rocking pin is rotatable about two different points.

A method of providing stability control augmentation to a flight control surface of an aircraft, comprising:
- providing a control valve comprising a spool and an integrated augmentation mechanism;
- increasing or decreasing a cross-section of a fluid flow path through the control valve by moving the spool to thereby increase or decrease a flow of hydraulic fluid to an actuator operable to actuate the flight control surface;
- and
- increasing or decreasing the cross-section of the fluid flow path using the augmentation mechanism to thereby adjust the flow of hydraulic fluid to the actuator;
- providing a rocking pin connecting the spool and the augmentation mechanism, and rotating the rocking pin about a first pivot to actuate the spool of the control valve and thereby increase or decrease the cross-section of the fluid flow path.
